Find the values of x and y.

hodyreva [135]

Answer:

C, (x = 100, y = 10)

Step-by-step explanation:

hi again,

(2x - 70) = (x + 30), by the Alternate Exterior Angles

x - 70 = 30

<em>x = 100</em>

<em />

(2x - 70) + 5y = 180, by the Linear Pair Theorem

2(100) - 70 + 5y = 180

200 - 70 + 5y = 180

130 + 5y = 180

5y = 50

<em>y = 10</em>

Answer:

A. Area in square inches = 1760 square inches

B. Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

Step-by-step explanation:

Given,

Length of the rectangle (l) = 55 inches

Breath of the rectangle (b) = 32 inches

A. Area of the rectangle = length × breath

⇒ 55 × 32

⇒ 1760 square inches

Area in square inches = 1760 square inches

B. 1 foot = 12 inches

1 inch = $\frac{1}{12}$ feet

1 square inch = $\frac{1}{144}$ feet

∴ 1760 square inches = $\frac{1760}{144}$ feet

⇒ 12.2222 square feet

Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet
